Common Failures
Common symptoms reported include unexplained faults when driving on hard stops and rapidly fluctuating current readings. Another issue involves field loss indications on the regulator board.
Repair Approach
We evaluate each unit to determine the root cause. Typical repairs may involve replacing the current transducer module when unexplained drive faults are present. For field loss problems on the regulator board, replacing the SCR module may be effective. Diagnostic testing and inspection are performed to isolate faulty components.
Testing & Quality
Repaired units are tested after components are replaced. Testing procedures include functional checks to verify that current output matches expected values under various drive conditions. Units that pass all testing phases are cleared for return to service.
